CD74HC4511PW

Display Drivers Overview

The CD74HC4511PW is a high-speed CMOS BCD-to-7-segment latch/decoder/driver manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features a propagation delay of 60 ns. The device supports a maximum output load capacitance of 50 pF with a maximum output current of 5.2 mA. It functions across an extended temperature range from -55°C to +125°C. The component is housed in a 16-pin TSSOP package, designed for surface-mount technology applications requiring efficient seven-segment display driving capabilities.

Display Drivers Feature Summary

• Integrates a four-bit latch to store BCD input data before decoding
• Decodes binary-coded decimal inputs into seven-segment outputs
• Provides direct drive capability for LED displays without external buffers
• Includes a lamp test input for verifying segment functionality

Display Drivers Applications

• Seven-segment LED numeric displays
• Digital counter readouts
• Instrumentation panel indicators
• Consumer electronic display modules

Display Drivers Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 16-TSSOP configuration. Confirm RoHS compliance status if required by assembly standards. Cross-reference the full part number with authorized distributors to validate availability and authenticity.

Display Drivers Selection Notes

Select this component when a dedicated decoder with integrated latching is required for seven-segment displays. The HC series offers standard speed suitable for most general-purpose digital systems. Consider the operating voltage range and temperature specifications to ensure alignment with the target application environment. Verify that the output current capability meets the requirements of the connected display segments.

Display Drivers Part Context

This device belongs to the Texas Instruments CD74HC4511 family of logic ICs. It is part of the broader 74HC series, known for high-speed CMOS operation. The family includes variants with different packaging options such as SOIC and TSSOP. These components are widely used in digital electronics for converting binary codes into human-readable numerical formats on display devices.

Display Drivers Replacement Considerations

Compatible substitutes include CD74HC4511PWR and CD74HC4511PWTE4. Verify pinout compatibility and electrical characteristics before substitution. Ensure the alternative part matches the required package dimensions and thermal performance.
